Trumpet Labs announces Josephine, the newest addition to their product
line of microphones handcrafted in Portland, OR. A medium-large
diaphragm (26mm) condenser microphone, Josephine, is designed for live
vocal and ensemble use, with an avant-garde styling evocative of 1930s
and 40s classic microphones. Josephine
is optimized for use by singers or acoustic ensembles from 6” to 48”
away. The design, form-factor, and sound are ideal for period swing or
jazz vocalists or single-mic techniques with bluegrass or traditional
musicians, with significantly better feedback rejection than the large
diaphragm condener's typically used in these applications.
Founder
of Ear Trumpet Labs, Philip Graham notes, “The original Josephine was
actually the first model that I designed, and the first affirmation of
the sound quality that was achievable with this capsule and circuit
design. We’ve learned a lot over the last two years about improving
feedback rejection and usability onstage. I’ve always loved Josephine’s
bold geometry and wanted to revisit it with a design that is extremely
practical for live stage use. I love that she’s sleek, eye-catching, and
incorporates all we’ve learned about building the best mics for live
acoustic music.”

Josephine
is a medium-large diaphragm (26mm) condenser microphone designed for
live vocal and ensemble use. The design features a spherical stainless
steel mesh headbasket spring-suspended in a six-inch diameter copper
ring. The design is an avant-garde take on classic microphone design of
the 1930s and 40s, and is made largely from standard hardware elements.
The head basket incorporates a very effective silk and foam pop filter
as well as Sorbothane shock and vibration damping to minimize handling
noise, and internal rubber baffles to shape the sound of the mic.
The
capsule is a Chinese-made electret condenser with additional acoustic
damping. Capsules are individually tested and selected – roughly 30% of
capsules are rejected for not meeting design criteria. The circuit is a
transformerless FET with fully balanced output and EMI noise
suppression. Other electrical components in the signal path are highest
quality metal film resistors, polypropylene and polystyrene capacitors,
and individually tested, hand-matched and biased transistors and JFETs.
The
circuit includes moderate bass rolloff to compensate for proximity
effect, and high frequency EQ to avoid harshness and help control
feedback. The cardioid polar pattern, headbasket design, and tuned
electronics all work together to make a very stable live mic with an
extremely natural sound and good feedback rejection. Josephine is
optimized for use by singers or acoustic ensembles from 6” to 48” away.
The styling, form-factor, and sound are ideal for period swing or jazz
vocalists or single-mic techniques with bluegrass or traditional
musicians, with significantly better feedback rejection than the LDCs
typically used in these applications.
